Downgrade of HCA firmware on all nodes in the EXAScaler cluster is mandatory. Contact DDN Support for assistance.
The free EXAScaler Log Agent (es_log_agent) replaces DDN Collect for EXAScaler customers.
Severe issues with performance, function, or system stability may arise if directory striping is enabled on directories but the large directory feature is not enabled on all MDTs.
Some normal uses of lfs_migrate may put EXAScaler data integrity at risk. See bulletin for further information.
System reboot may cause data synchronization issues between the local S3 Data Services container storage and mounted EXAScaler file systems.
A file size handling bug in the Lustre kernel can put data at risk in EXAScaler files using the hot pools feature.
See bulletin for workaround instructions.
Security issues in Samba can break authentication, inject code into long DCE/RPC messages, and force root takeover by Active Directory. Workarounds are provided.

DDN EXAScaler Product Family: EXA6 Data Sheet
Artificial Intelligence (AI), Analytics and High-Performance Computing (HPC) enable organizations everywhere to gain insights from their data with unprecedented velocity and accuracy. Data-intensive workflows put storage infrastructure squarely in the critical path—driving requirements for extreme, dependable performance that scales easily to meet evolving workload requirements on premise and in the cloud.
Developed and optimized using the latest advances in filesystem software technology, EXA6 delivers extreme performance, scalability, capability, reliability and simplicity.
Augmented with feature-rich enhancements, EXA6 delivers a true global data platform capable of enabling and accelerating a wide-range of data-intensive workflows, at any scale. Fully-integrated DDN EXAScaler appliances combine the world’s fastest hyperconverged data storage platform with a truly parallel filesystem software in a package that’s easy to deploy, managed and backed by the leaders in data at scale.
EXA6 is fully-optimized to deliver data with high-throughput, low-latency and massive concurrency using a shared parallel architecture that can scale flexibly bringing dramatic performance and economic benefits. Building on over a decade of experience deploying parallel filesystem solutions in the most demanding environments around the world, DDN delivers unparalleled performance, capability and flexibility for users looking to manage and gain insights from massive amounts of data.
EXAScaler includes new data management and integrity filesystem features developed by DDN and only available in its appliances and cloud offerings. Stratagem is a powerful data orchestration engine that gives users comprehensive data residency controls using policy-based placement.
Hot Nodes capability accelerates data access further, by automatically caching data on the local NVMe of GPU systems, reducing IO latency and traffic by avoiding network round trips, and freeing up infrastructure to serve additional workloads.
Hot Pools intelligently moves data between high-performance flash and large capacity disk and ensures efficient use of storage. A native T10DIF implementation ensures that data is handled with full integrity from application to disk. EXAScaler enables organizations everywhere to create, analyze and manage more data than ever before, accelerating time-to-insight with unequalled performance for the most demanding workloads on premise and in the cloud.
